Title: Improved percussion fuse for projectiles
IPC: F42C9/02
Filed: 1926-12-02
Abstract: 271,344. Junghans, O. Dec. 2, 1926. Projectile fuzes.- Clockwork safety devices are driven by centrifugal force in a manner similar to the known centrifugal drives of clockwork time fuzes. In the form shown, bolts 5, normally retained in the forward locking position by a yoke spring 6, shoot back by inertia on discharge and release a balance 7 and radial bolts 3. These bolts move out by centrifugal force and release a direct-impact striker 1, which is moved forward by a spring 4 out of a hole 21 in a sector 8. This sector then swings round bv centrifugal force; but this movement is delayed by a clockwork comprising the balance 7, an escapement wheel 16, pinions 15, 14, 13, and a toothed quadrant 12 fast on the spindle 10 of the sector 8. The movement is also delayed by the pressure of a spring bolt 18 beneath the sector 8. At the appointed time, the sector 8 brings a detonator Z in line with the striker 1, and allows the spring bolt 18 to rise into the hole 21, whereupon another sector 19 is released. This sector normallv obstructs the passage from a primer charge S to a primer charge U<2>, but when released it swings round by centrifugal force and brings an intermediate priming charge U' between the charges S, U<2>, thus completing the arming of the fuze.

Filed: 1938-10-24
Abstract: 521,196. Yarns &c. BRANDWOOD, J. Oct. 24, 1938, No. 30636. [Class 120 (iii)] [Also in Group IV] Yarns of soft and lustrous character are obtained by treating textile rovings or slubbings with weak solutions of substances having cohesive properties so as to impart increased frictional resistance to separation without fixed cohesion of the component fibres when dried, clearing excess solution as far as possible from the fibres, and then drying. The strength of the solution used is such that while it gives increased frictional resistance to separation of the fibres sufficient to enable the yarn so obtained to withstand winding and weaving tension, there is no perceptible film or coating upon the fibres, which are in physical contact. Solutions or dispersions of rubber latex, cellulose derivatives, gellatose, a soluble starch, or gums, may be used. The strength of the solution may be 0À5-1 per cent. The cohesive material may be incorporated in a dye bath or a subsequent, washing bath, or the treatment may be carried out separately. The solution may be passed through the roving by differential pressure and clearance of excess of solution may be effected by compressed air. Specification 482,817 is referred to.
